Public award description
WE OFFER A PLASMA CATHODE FOR MICRO HALL AND ION THRUSTERS OF UNPRECEDENTED POWER EFFICIENCY, LOW COST, COMPACTNESS, AND DURABILITY. IT EMPLOYS, AMONG OTHERS, A VERY SMALL PLANAR SCANDATE CATHODE AS ELECTRON SOURCE. THIS IS A REVOLUTIONARY CATHODE TECHNOLOGY ONLY RECENTLY PERFECTED BY E BEAM INC. IT IS CAPABLE OF DELIVERING OVER 350 MA OF DISCHARGE FROM AN EMITTER AREA ONLY 0.012 CM2. EFFICIENCY IN DISCHARGE IS MEASURED TO BE>70 MA/WATT OF INPUT POWER. THIS INNOVATION AVOIDS CONVENTIONAL HOLLOW CATHODE KEEPER GEOMETRIES, WHICH ARE TOO EXPENSIVE, USE TOO MUCH POWER, AND ARE DIFFICULT TO MINIATURIZE. THE PHASE I SCANDATE CATHODE RAN ABOUT 1000 HOURS IN CW DISCHARGE AT 350 MA WITH NO DROP IN EMISSION OR FUNCTIONALITY.
